MX4800 with R4 tires. About 6.5 ft with the ROPS down. I didn't fold it, I just assume Not much sticks up above the hinge. But, way under 7 ft.
Will clear an 8 ft door with the ROPS up, but not by more than a couple of inches.
Be aware the BH92 backhoe WILL NOT clear an 8 ft door with the boom all the way up. My door has the scars to prove it.
